Class 'Horario' is not defined / Class 'Horario' has no 'objects' member
I keep getting this error and I can't seem to find the proper answer to it. I have created a model in models.py class Horario(models.Model): dia = models.CharField(max_length=20) mañana = models.CharField(max_length=20) tarde = models.CharField(max_length=20) and now I am creating a view in views.py to render this in a html file that I have called horario.html def horario(request): context = {'horario' : Horario.objects.all()} return render(request, "horario.html", context) The thing is that I keep getting this error. I have read other threads and the correction to this error seems to be pasting this code in settings.json {"python.linting.pylintArgs": [ "--load-plugins=pylint_django" ],} I don't know how to do this since as I do it I get random errors. Anyone knows a proper way to get this done? -

Conditional Execution in Same View
I want my declarations to be user-specific. I chose to do this by making my variable declarations in the view conditional based on user-type. Here's a sample. def order_detail(request, order_id): order = get_object_or_404(Order, id=order_id) if request.user.is_supervisor: user_location = request.user.supervisor.town deliverer = User.objects.filter(deliverer__town=user_location) context={ 'order': order, 'all_delivery_guys_in_town': deliverer } template = 'orders/order_mgt/detail.html' return render(request, template, context) For context, I need supervisors to be able to view a list of available delivery guys within the order detail page. In the code sample, I'm getting an error: local variable 'user_location' referenced before assignment 1. How can I correct this error? 2. Is there a better way of making conditional declarations within the same view? -
Select multiple rows from list to perform action

For now, I can edit or delete row for row. <div class="table-responsive"> <table class="table table-bordered"> <thead class="thead-dark"> <tr> <th scope="col">Select Multiple</th> <th scope="col">Col 1</th> <th scope="col">Col 2</th> <th scope="col">Col 3</th> <th scope="col">Col 4</th> <th scope="col">Edit</th> <th scope="col">Delete</th> </tr> </thead> <tbody> <tr> <td>{{ object.selectedOrNot }}</td> <-- BooleanField? <td>{{ object.value1 }}</td> <td>{{ object.value2 }}</td> <td>{{ object.function1 }}</td> <td>{{ object.function2 }}</td> <td><a href="{% url 'edit' object.id %}">Edit this row</a></td> <td><a href="{% url 'delete' object.id %}">Delete this row</a></td> </tr> </tbody> </table> </div> My Question is: How can I make them selectable (checkbox), to multiple delete or edit desired entries. -
Django, how to get total sum of methods with agregate sum
how to get total sum of methods in django using agregate ? I used this for fields and it work fine but for method it doesn t return anything. class Invoice(models.Model): date = models.DateField(default=timezone.now) client = models.ForeignKey('Client',on_delete=models.PROTECT) def total(self): total = self.invoiceitem_set.aggregate(sum=Sum('subtotal')) return round(total[("sum")] or 0, 2) class InvoiceItem(models.Model): invoice = models.ForeignKey('Invoice', on_delete=models.CASCADE) product = models.ForeignKey(Product, on_delete=models.PROTECT) price = models.DecimalField(max_digits=20, decimal_places=2) quantity = models.DecimalField(max_digits=20, decimal_places=2) def subtotal(self): return self.price * self.quantity -
Django testing database in a restricted environment
as the title says, I'm restricted in my development environment. I cannot create extra databases for testing purposes and only create local files. Using the environ package for django, the configuration of the database is DATABASES = { 'default': env.db('DATABASE_URL', default='postgres://name@localhost'), } As found in this thread, all I need is a "TEST" key in this configuration. It doesn't have one per default so I've bypassed this by writing db = env.db('DATABASE_URL', default='postgres://name@localhost') db["TEST"] = { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), } This doesn't work however. python manage.py test gives me the following output: Creating test database for alias 'default'... /usr/lib/python2.7/dist-packages/django/db/backends/postgresql/base.py:267: RuntimeWarning: Normally Django will use a connection to the 'postgres' database to avoid running initialization queries against the production database when it's not needed (for example, when running tests). Django was unable to create a connection to the 'postgres' database and will use the default database instead. RuntimeWarning Got an error creating the test database: permission denied to create database Type 'yes' if you would like to try deleting the test database '/home/<closed environment>/<project>/config/db.sqlite3', or 'no' to cancel: It still tries to create a database inside an environment in which I do not have the power to alter my … -
How do we display the elements in the dictionary passed as a context object to Django and remove them as user selects it?
I want to display the elements passed through the context object and allow users to unselect or remove items they don't want and submit the form with the remaining items. I am new to Django, I know this could have been done in React using state variable. I tried the following- <select id="mySelect" size="{{mems|length}}"> {% for mem in mems %} <option> {{mem.user}} </option> {% endfor %} </select> <button onclick="myFunction()">remove</button> <script> function myFunction() { var x = document.getElementById("mySelect"); x.remove(x.selectedIndex); } </script> It updates the UI for a second and then again reverts back to the starting state because I guess the mem object is not getting modified in this case and hence again renders the complete list. Is there a better option to display these details and manipulate the DOM based on the requirements in Django? ->mems here is the result of a DB query and has objects with reference to the user model. What I want to return to the server-side is these users, which the admin selects. -
POST request giving KeyError Django DRF

django is_active does not disable the user
I have a Django project that is like a blog and only a few people are using its panel. There was a user that about 5 people where using and we decided to disable this user and create separate accounts for them. In order to prevent errors in the future we decided just to disable this user and not to delete it. I did it manually using the Django's admin panel. I changed is_active to false but the user still is active and can login to the blog panel. Can you please help me find what is the reason? -
How to update a django moodel value from a button click in a class view
i currently have a model that looks like: Model class Answer(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE, related_name='answers') author = models.ForeignKey(User, on_delete=models.CASCADE) content = models.TextField() date_posted = models.DateTimeField(default=timezone.now) is_best_answer = models.BooleanField(default=False) def set_best_answer(self): self.is_best_answer = True self.save() def get_absolute_url(self): return reverse('question-detail', kwargs={'pk': self.question.pk}) def __str__(self): return f"Answer by {self.author} with text: {self.content}" I have a Class based Listview which lists all of the answers above. I want to add a button in the template that would update the value in the model of is_best_answer to True e.g. html <a class="btn btn-outline-dark " href="{% url 'select' answer.id %}">Set Best Answer</a> view def set_best_(request, pk): answer = Answer.objects.filter(pk=pk).first() answer.set_best_answer() return redirect('/') url path('answer/<int:pk>/best-answer/', set_best, name='select'), The above works for me, but i have had to call a function rather than anything to do with the class based views.

JSONFIeld(null=True): Is allowing null bad practice?
It's my first time working with Django's JSON fields. When going through examples I usually see the field implementations that set the default to an empty object. However, for my purposes, I'd prefer to allow the field to be None as well. Since all the examples set a default, I'm not sure if allowing null will yield any negative consequences I'm unaware of currently. -

Issue with POST email, returning to same page, templates and httpresponse
First of all, I only started using Django a week ago... so pretty new :). I have a one page website. At the bottom there is a contact form. I am using different components for the website, so for the contact form I have 'contact.html' which is loaded into index.html via {& include ... &}. When someone sends a message via contact form, after click send, the user returns to the same page but with a thank you message instead of the contact form (see screenshot). The issue is that I need to 'kill' the process going on underneath because if I reload the page a message pops and if I resubmit, email gets resend again (see screenshot). I have had a look at httpresponse but I am unsure how to replicate the same process. Anyone could help? This is a screenshot of contact.html and views.py -
